First of all many thanks to all of you spending time to write such detailed answers. I appreciate it very much. From my view I see 3 options:

1. 956/960 from Premacon, RTR, very detailed and realistic model BUT expensive and long delivery time
2. Volvo 480 from THS. RTR, very detailed and realistic as well and long delivery time.
3. Komatsu PC490 from Fumotec. i have heard many positive customers recommending Fumotec. it's not possible to have it RTR so I need to assemble the excavator myself. can be a good learning and the price is half as Premacon and THS

The price is absolutely one factor but not the only. I would like to have a machine which is both strong AND realistic but movements, lights, sound, details etc.
